Universal Soldier

During the Vietnam War, soldier Luc Deveraux (Jean-Claude Van Damme) finds that his superior officer, Andrew Scott (Dolph Lundgren), has turned violently deranged, and the two fight to the death. After their bodies are retrieved, they are placed into a secret program in which they are reanimated and trained to become unquestioning killing machines. While Devereaux and Scott initially have no memory of their former lives, glimpses of their pasts start to return, rekindling their intense conflict.
